80 GB is in the range of what I think of as "barely manageable" on your
average midrange Unix computer (IBM H80, Sun E450).  I know folks run
bigger DBs (somebody's got one in excess of 160GB) but you need
substantial server hardware and very fast disks.

        Subject:        TSM database maximum recommended size


Hello all,

Our data storage requirements have been driving our TSM database usage to
new heights, and we are looking for some references to "just how big is
too
big" in order to help build a business case for deploying additional
servers.

Our current TSM database is 86.5GB and although backup and restore
operations are running fine, database management tasks are becoming
painfully long.  I personally think this database size is "too big".  What
are your thoughts?
How many sites are running with databases this large or larger? On what
hardware?

IBM/Tivoli's maxiumum size recommendations seem to grow each year with the
introduction of more powerful hardware platforms, but issues such as
single
threaded db backup and restore continue to pose problems to unlimited
growth.

Any input would be greatly appreciated.

Thanks,

Scott.
